T 0 all fwn-0m it may concern.'

Be it known that I, GEORGE ALEXANDER MINETTY, a citizen of the United States, residing at Davenport, county of Scott, and State of Iowa, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a specification.

This invention relates to dumping cars in general and is particularly concerned with an improvement in the manner of mounting Yoscillating hoppers thereon.

It is sought in the present invention to provide a dumping car having companion hoppers arranged longitudinally of the car and adapted to be oscillated outwardly to discharge the contents thereof on either side of the car tracks; to so arrange said hoppers with respect to each other that only a minimum of space upon the car body will be wasted, in order to utilize as far as po'ssible all the car body for carrying purposes; and so mount the hoppers that they will normally tend through the action of gravity alone to remain swung inwardly against suitable stop members in upright carrying position.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawing, Figure l is a plan view of a dumping car constructed in accordance with the present invention; Fig. 2 is an enlarged end elevation of the same showing the hoppers in their normal upright position; and Fig. 3 is a view similar to Fig. Q showing the hoppers oscillated to discharging position.

There is shown in the drawing, a pair of companion hoppers t extending substantially the length of a car, upon the end sills 5 of which suitable supporting brackets 6 are placed. A stub shaft or trunnion 7 is positioned upon each end of each hopper upwardly and outwardly with respect to its center of gravity, and is adapted to seat within a suitable journal 8, one of which is carried upon each ofthe said brackets. The oscillating movement of the hoppers either simultaneously or separately is effected as by means of actuating levers 9 operated as through the medium of piston mechanisms 10. ln order that the hoppers may be further supported suitable arcuate shaped bearing members 11 may be secured to the car body having a portion 12 thereof adapted to engage with the underside of each hopturn to their normal upright positions.

per, intermediate -its ends and adapted, if desired, to limit the outward oscillating movement thereof. Stop members 18 may be placed, as shown, to determine the proper upright position of each of thehoppers when permitted to swing by gravity into its normal carrying position. When constructed in the manner shown, the hoppers are capable of `swinging through an arc of at least 135 degrees to a position, such as 1s indicated in Fig. 8. This oscillating movement is accomplished without in any way shifting the position of the hoppers, except as they revolve upon their trunnion supports. The material which the said hoppers are designed to carry will be completely discharged upon oscillation thereof to such a position. When, however, the hoppers are in their normal upright positions, as shown in Fig. l, the material contained therein may be safely carried without danger of being spilled or lost.

It is to be particularly noted that the suspension supports for each of the hopners is located upward-ly and; outwardly with respect to the axes of gravity thereof, this manner of support tending normally to maintain the hoppers in an upright position against the members 13. When completely oscillated to the extent shown in Fig. 3, the aXis of gravity of each of said hoppers still remains in such position with respect thereto that, upon withdrawal of the actuating forces, the hoppers will tend of their own accord to swing around by gravity and re- The lines m and y at their intersection represent substantiallv the axis of gravity of each of said hoppers and is seen always to be inwardly disposed with respect to the trunnions upon which the hoppers revolve. The return of the hoppers to their upright position is effected merely by releasing the pressure in the piston mechanism and without employment of positive means therefor.

1 claim:

1. In a dumping car, the combination of outwardly swinging box-like hoppers eX- tending longitudinally thereof, stop members for preventing inwardlv swinging movement of said hoppers beyond an upright 1iosition thereof, suspension supports for said hoppers, located at the ends thereof, outwardly andv upwardly with respect to their axes of gravity whereby they tend normally to remain in upright position against said stop members, and auxiliary supporting means for said hoppers intermediate the ends thereof, substantially as described.

2. In a dumping car, the combination of outwardly swinging box-like hoppers eX- tending longitudinally thereof, stop members for preventing inwardly swinging movement of said hoppers beyond an upright position thereof, suspension supports for said hoppers, located at the ends thereof, outwardly and upwardly with respect to their axes of gravity, whereby they tend normally to remain in upright position against said stop members, and auxiliary supporting means for said hoppers inter` mediate the ends thereof, comprising bear ing members carried by the car body and adapted to engage with the under side of said hoppers, substantially as described.

3. In a dumping car, the combinationof outwardly swinging box-like hoppers exv to their axes of gravity, whereby they tend vnormally to remain in upright position against said stop members, and means for limiting the outwardly swinging movement of said hoppers to prevent a preponderance of weight of the hopper bodies from lying outwardly with respect to their axes octl gravity, substantially as described.
